CHARLES W. HUTGHINSON, OF NEW YORK, N. Y.

WINDOW-SHADE FIXTURE.

Specification. of Letters Patent.

Application filed August 12, 1913. Serial No. 784,357. I i

To all whom it may concern:

Be it known that I, OrIAnLns /V. Huronnson, a citizen of theUnitedStates, residing in the borough of Manhattan, city of New York, in thecounty of New York and State of New York, have invented certain new anduseful Improvements in VVindow- Shade Fixtures, of which the followingis a specification, reference being had therein to the accompanyingdrawings, forming part thereof.

My invention relates to fixtures for window shades, and particularly tofixtures which are constructed so that the shade is.

carried along part of the way with the sash as the sash is opened, asfor ventilation, and is then automatically released from the sash and iscaught again by the sash as the sash is moved back. Suchfixtures aredescribed and claimed in my prior Patent, No. 1,059,-

964, of April 22, 1913. In the construction there shown, no provisionwas made for en abling the two sashes of a double sash window. to passeachother since the shade-sup porting brackets which were carried by theupper sash would prevent the lower sash co-pending application, No. 767,549, filed Mayl l, 1913, I have shown and described a constructionwhereby the shade is automatically transferred from the upper sash tothe lower sash as the two sashes pass, and isagain transferred to theupper sash as the sashes pass in the return direction.

This invention is an improvement upon.

theIco-nstruction disclosed in my said copending application, and anobject of my invention is to provide a simple, reliable and durablebracket structure which will be positively carried by the upper sashwithin the range of movement of the shade and which will be easily andreliably removed therefrom and supported when the limitflof the movementof the shade isreached or when the two sashes pass each other- Anotherobject of my inventionis to pro vide suitable means for preventing inury to the shade-supporting brackets by the lower sash. v

Another object is to provide means, operative at the option of theoperator for holding the shade in its upper position as the sash islowered.

Other objects are inexpensiveness ofconstruction and convenience ofoperation.

Still other objects and advantages of my invention will appear fromthefollowing :descnptmn.

In accordance with my invention, I provide automaticallyreleasable-means for attaching the brackets to the sash whereby upwardpressure uponthe brackets, such as is developed when the brackets strikethe lower sash or their limiting stops, will automatically release thebrackets from the upper sash.

will hold the brackets when they are released from the sash. Morespecifically, the brackets have attaching portions which hook over thewindow sash, and to move the brackets down with the sash, abutmcnts areprovided onthc sash under which yieldable locking members engage,-thelocking members beingadapted to yield and release the brackets when thebrackets are pressed upwardly with suflicient force. To prevent thelower sash from being raised high enough to jam or injure thebrackets,jointed stops are arranged in the path of the lower sash just below theuppcrmostposition of the brackets. These jointed stops are out of thepath of the brackets when they are turned down, but when turned outextend into the path of the brackets, and thcy may thus be turned outand prevent the brackets from being moved upwardly with the sash if itis de- Patented Oct. 27,1914;

I also provide retaining guides for v the brackets upon the windowframes, which sired to retain the shadein its uppermost other featuresOfCOIlStlllCtlOll and details and arrangements ofparts, as willhereinafter more fully appear. a j I shall now describe the embodimentof my invention illustrated in the accompanying drawings and shallthereafter point out m invention in claims.

Figure 1 is a vertical sectional elevation taken on the line of section1.-1 of Fig. 3 of the upper portion of a window sash and frame withfixtures embodying my invention. Fig. 2 is a similar view showing thesash lowered and the shade released. Fig. 3 is a plan of the same withthe top of the window frame removed and the middle portion broken away.Fig.4 is a front elevation of the same with the central portion brokenshowing the sashes passed and the parts in their resultant positions.Figs. 6 and 7 are details on an enlarged scale of the attaching end oione of the brackets, Fig. 6 being a side elevation and Fig. 7 being afront elevation.

in the illustrated embodiment of my invention, each of the bracketswhich are carried on opposite sides of the upper sash 1, comprises aflay metal outstanding arm or supporting plate 2 arranged with its fiatfaces vertical and provided at its outer end with a longitudinal slot 3and provided at its. inner end with an integral attaching portion. Thisattaching portion is hook shaped and is adapted to hook upon the top ofthe sash to support the bracket, and comprises aflat vertical portion orplate extending up from the supporting arm 2 and disposed at rightangles thereto so as to lie flat against the sash 1, and an overhangingportion 5 integral with the vertical portion and provided with adownwardly turned flange 6 at its rear end and adapted to engage uponthe top of the sash 1. For the reception of this overhanging portion 5and the flange 6, the sash 1 is rabbeted at its inner edge, and at therear edge of this rabbeted portion, agroove 'i' is provided for thereception of the flange 6. This rabbeted portion may be protected by ametal wearing plate, as shown in the drawings. A brace 8 may extendbetween the supporting arm 2 and the vertical arm t of the attachingportion to strengthen the bracket. Thus the brackets may be attached tothe upper sash by hooking their overhanging portion on the top of thesash. To assure that the brackets will be moved down with the sash asthe sash is lowered, an abutment member is provided on the sash for eachbracket. in the illustrated embodiment, tl abutment member comprises anabutment pin 9, and yieldable means are provided on each bracket forengaging underneath the respective abutment pin. At the bottom of thevertical portion of plate a on the side opposite the supporting arm 2, ashort outstandingflange 10 is provided, and a locking arm 11 is pivotedto this flange 10 and extends upwardly and engages with its upper endunderneath "the abutment pin when the bracket is in place on the sash.The engaging faces of the abutment pin 10 and of the locking arm 11 arerounded off so as to provide cam faces, and consequently an upwardpressure on the bracket tends to force the pivoted locking arm 11outwardly from under the abutment pin 9 and thus release the bra ketfrom the sash.

To hold the locking arm underneath the pin while permitting it to yieldunder suit} cient pressure, a fiat spring 12 is provided, which issecured at its lower end'to the bottom of the vertical plate a and bearswith its upper end against an angularly extending arm 11 on the lockingarm 11. This angularly extending arm 11 is bent around in front of thevertical plate land is preferably arranged in a plane somewhat in frontof tne plate 4, so as to assure that the locking arm 11 will be heldunderneath the abutment pin 9 in case the window sash is loose in theframe. The spring 101 is sutliciently stiff to hold the locking arm 11underneath the abutment pin 9 against the ordinary friction as thewindow sash is lowered within the range of movement of the window shade,but in case a rigid stop is encountered by the bracket, the spring 12will yield and permit the locking arm to escape outwardly from. underthe abutment pin 9 and release the shade from the sash as the sash moveson.

To guide the brackets in their movement, two guide members are providedfor each bracket,'s ecured upon the respective sides of the windowframe, an inner guide member 13 which is secured on the parting stripll,

and an outer guide member 15 secured upon the guide strip 16. These.guide members have their longitudinal sides bent up to acute angles toform undercut guide grooves open at their upper ends and closed at theirlower ends. The guide membersare straight and are arranged substantiallyvertical and parallel, the outer guide member being somewhat longerthan'the inner guide mom-- ber for a reason which will hereinafterappear. 1

Two shades are shown supported upon the brackets, although it is evidentthat only one shade need be used if desired. The spindles 17 of theshades on each end of the shades enter into spindle receivingperforations in a shade carrying platelS. This is an elongated flatplate provided, in the construction shown, with two guide studs 19, oneabove each spindle receiving. perforation, which are riveted orotherwise secured to the plates, and have flaring plane sided guideheads shaped to lit in the guide groove and slide freely therein, whilebeing,prevented from escaping therefrom except at the open end of thegroove. Near its upper end, the plate 18 is provided with a headed lug20 which extends through the slot 3 of the respectivebracket arm 2,thereby connecting the arm 2- with the shade carrying plate 18. This lug520 is preferably removable and screws into the plate 18. At its innerend, the supporting arm 2 of the bracket is also provided with a guidestud 19 which engages in the guide groove of the guide member 13. Thusthe bracket is guided at its inner and outer ends and is re tained inplace when released from the sash 1, the guide members serving both asguiding and retaining members. a

The outer guide member 15 is of such length that the lower shade spindle1'? strikes the bottom of the groove, it theshade spindle is ofsuilicient length to extend into the groove, otherwise the lower guidestud 19 strikes the bottom of the slot, at the same timethat the guidestud 19 at the inner end of the supporting arm 2 strikes the bottom ofthe inner groove 13. The closed bottom of these grooves thus serve aslimiting stops to the downward movement oi theshades. It will be notedthat the slot 3 in the arm 2 is elongated to enable the arm to be usedin window frames of various widths.

It will now be understood that as the sash l T is lowered, the bracketand hence the shades are lowered with it until the bottoms of the guidegrooves are engaged when the shade supporting brackets are picked offfrom the sash and left behind, yieldingoutwardly against the tension ofthe spring 12 to escape past the abutment pin 9.

Should the lower sash pass the upper sash within the range of movemcntof the shades, it isapparent that the lower sash will then serve as astop and will pick the brackets off the uppersash, as is done when theguide studsstrike the bottoms of the guide grooves. This condition isillustrated in Fig. 5 in which the bracketis shown as resting upon thetop of the lower sash 21,

the upper sash being lowered and the bracket released therefrom. Thebrackets are retained in posltion by theretaimng guide grooves, ready tobe again pickedup by the upper-sash. "Thus the sashesmay be readily andfreely reversed, as is required in washingwindows. j j

Should 1t lOG ClQSII'GCl to lower the upper sash 1 wlthout carrying the;shades down with it toprovide ventilating space, I provide on each sideof the framein the path of the lower sash a jointed stop 22, which islocated just below the respective bracket arm 2 in itsuppermostposition, and is adapted to be folded down against the frame out of thepath of the bracket arm so as to permit the respective bracket armtopass, as shown in the drawings; or which can be turned :or openedloutand in that position will project into the path of the bracket arm andwill serve to pick OK the bracket at the beginning of the openingmore-meat of the upper sash, and the shades will thus be left in theirnormal positions, These jointed stops 22 also serve to limit the upwardmovement of the lower sash. and thus prevent the lower sash from beingcarelessly elevated and striking and in;- juring the brackets.

It is obvious that various modifications may be made in the constructionshown in the drawings and above particularly described, within theprinciple and scope of.

my invention.
